Definitions

  • the invention relates to a gas distribution assembly, including medical gas, comprising a gas cylinder, a valve block attached to the gas cylinder and a protective cowling arranged around said valve block and comprising an electronic display screen allowing the information display, being housed in the upper part of said protective casing.
  • Gas containers typically gas cylinders, equipped with a valve block, with or without built-in expansion valve, namely a single tap open / closed type or an integrated pressure regulator valve, also called RDI, to control flow and pressure of the delivered gas.
  • RDI integrated pressure regulator valve
  • a protective cover forming a protective shell around said valve block.
  • hat cowling
  • the bottle / cap / tap assembly to be hooked to a support, such as a hospital bed bar, a stretcher, a rod or support for attaching an emergency vehicle, for example a SAMU unit or the like, it is customary to arrange on the cap, a fixed attachment system or mobile, including pivoting.
  • a support such as a hospital bed bar, a stretcher, a rod or support for attaching an emergency vehicle, for example a SAMU unit or the like
  • cowling In order to facilitate the transport and the handling of the bottle / valve block / cowling assembly, it is customary to provide the cowling with a carrying handle which, in general, overcomes it and allows it to be carried manually by users. .
  • Cowlings of this type are described in particular by the documents EP-A-629812 , DE-A-10057469 , US-2004/020793 and EP-A-2586481 .
  • a gas pressure indicator device such as a manometer, or gas autonomy that is attached to the valve block or RDI.
  • the document EP-A-2339222 teaches a gas cylinder equipped with a protective shell arranged around only the bottle body, which is provided with carrying handles.
  • a screen is arranged in the side body of the shell and allows monitoring the temperature of the gas in the container.
  • the valve block is not protected by any cowling, which generates risks of deterioration thereof, in case of fall or shock, and also the lateral arrangement of the screen on the hull limit greatly the ease of reading the information displayed.
  • the document EP-A-2339222 teaches a gas distribution assembly comprising a gas cylinder comprising a cowling covering the top of the bottle.
  • the valve block protrudes out of the cowling.
  • Two transport handles, attached to the cowling, are arranged laterally and on either side of the valve block.

Description

L'invention porte sur un ensemble de distribution de gaz, notamment de gaz médicaux, comprenant une bouteille de gaz, un bloc robinet fixé sur la bouteille de gaz et un capotage de protection agencé autour dudit bloc robinet et comprenant un écran à affichage électronique permettant l'affichage d'informations, venant se loger dans la partie supérieure dudit capotage de protection.The invention relates to a gas distribution assembly, including medical gas, comprising a gas cylinder, a valve block attached to the gas cylinder and a protective cowling arranged around said valve block and comprising an electronic display screen allowing the information display, being housed in the upper part of said protective casing.

Les gaz industriels et médicaux sont couramment conditionnés dans des récipients de gaz, typiquement des bouteilles de gaz, équipés d'un bloc robinet, avec ou sans détendeur intégré, à savoir un robinet simple de type ouvert/fermé ou un robinet à détendeur intégré, encore appelé RDI, permettant de contrôler débit et pression du gaz délivré.Industrial and medical gases are commonly packaged in gas containers, typically gas cylinders, equipped with a valve block, with or without built-in expansion valve, namely a single tap open / closed type or an integrated pressure regulator valve, also called RDI, to control flow and pressure of the delivered gas.

Afin de protéger ce bloc robinet, il est courant d'agencer au niveau du col de la bouteille de gaz et autour dudit bloc robinet, un capotage de protection formant coque protectrice autour dudit bloc robinet. Un tel capotage est couramment appelé « chapeau ».In order to protect this valve block, it is common to arrange at the level of the neck of the gas bottle and around said valve block, a protective cover forming a protective shell around said valve block. Such a cowling is commonly called "hat".

Par ailleurs, pour permettre d'accrocher l'ensemble bouteille/chapeau/robinet à un support, tel un barreau de lit d'hôpital, un brancard, une tringle ou support d'accrochage d'un véhicule d'urgence, par exemple une unité de SAMU ou analogue, il est usuel d'aménager sur le chapeau, un système d'accrochage fixe ou mobile, notamment pivotant.Moreover, to allow the bottle / cap / tap assembly to be hooked to a support, such as a hospital bed bar, a stretcher, a rod or support for attaching an emergency vehicle, for example a SAMU unit or the like, it is customary to arrange on the cap, a fixed attachment system or mobile, including pivoting.

Afin de faciliter le transport et les manipulations de l'ensemble bouteille/bloc robinet/capotage, il est usuel de doter le capotage d'une poignée de transport qui, en général, le surmonte et permet son portage manuel à une main par les utilisateurs.In order to facilitate the transport and the handling of the bottle / valve block / cowling assembly, it is customary to provide the cowling with a carrying handle which, in general, overcomes it and allows it to be carried manually by users. .

Des capotages de ce type sont décrits notamment par les documents EP-A-629812 , DE-A-10057469 , US-A-2004/020793 et EP-A-2586481 .Cowlings of this type are described in particular by the documents EP-A-629812 , DE-A-10057469 , US-2004/020793 and EP-A-2586481 .

Il est connu de fournir à l'utilisateur des informations relatives au gaz délivré par la bouteille (type de gaz, pression, autonomie....).It is known to provide the user with information relating to the gas delivered by the bottle (type of gas, pressure, autonomy, etc.).

Pour ce faire, on peut utiliser un dispositif indicateur de pression de gaz, tel un manomètre, ou d'autonomie en gaz qui vient se fixer au bloc robinet ou RDI.To do this, one can use a gas pressure indicator device, such as a manometer, or gas autonomy that is attached to the valve block or RDI.

Or, le positionnement de ce dispositif en partie basse du robinet, du fait de contraintes techniques, notamment du fait que le capotage de protection entoure le bloc robinet ou RDI, fait qu'il est souvent difficile ou peu aisé de lire les indications données par le dispositif, ce qui conduit inévitablement à des erreurs de lecture qui peuvent engendrer des ruptures de l'approvisionnement en gaz car l'utilisateur peut, en cas de mauvaise lecture, ne pas constater que la bouteille de gaz est vide ou presque vide.However, the positioning of this device in the lower part of the valve, due to technical constraints, including the fact that the protective cover surrounds the valve block or RDI, makes it often difficult or not easy to read the indications given by the device, which inevitably leads to read errors that can cause breaks in the gas supply because the user can, in case of misreading, not find that the gas cylinder is empty or almost empty.

De plus, si fournir à l'utilisateur des informations relatives au gaz délivré par la bouteille (type de gaz, pression, autonomie) est important, ces informations ne sont pas suffisantes et les utilisateurs ont de plus en plus besoin de disposer d'autres informations utiles (date, heure, lieu, nom de l'hôpital...).Moreover, if providing the user with information relating to the gas delivered by the bottle (type of gas, pressure, autonomy) is important, this information is not sufficient and the users have more and more need to dispose of other useful information (date, time, place, name of the hospital ...).

Or, il n'existe pas actuellement d'ensemble de distribution de gaz équipé de dispositif permettant de fournir une grande diversité d'informations à un utilisateur.However, there is currently no gas distribution assembly equipped with a device for providing a wide variety of information to a user.

Par ailleurs, le document EP-A-2339222 enseigne une bouteille de gaz équipée d'une coque protectrice agencée autour uniquement du corps de bouteille, laquelle est munie de poignées de portage. Un écran est aménagé dans le corps latéral de la coque et permet de surveiller la température du gaz dans le récipient. Toutefois, le bloc robinet n'est pas protégé par un quelconque capotage, ce qui engendre des risques de détérioration de celui-ci, en cas de chute ou de choc, et par ailleurs l'agencement latéral de l'écran sur la coque limite grandement la facilité de lecture des informations affichées.In addition, the document EP-A-2339222 teaches a gas cylinder equipped with a protective shell arranged around only the bottle body, which is provided with carrying handles. A screen is arranged in the side body of the shell and allows monitoring the temperature of the gas in the container. However, the valve block is not protected by any cowling, which generates risks of deterioration thereof, in case of fall or shock, and also the lateral arrangement of the screen on the hull limit greatly the ease of reading the information displayed.

En outre, le document US-A-5,440,477 propose une bouteille de gaz équipée d'un système de management de gaz formé d'un boitier électronique à écran venant se monte autour du bloc robinet. Ce système de management permet de gérer les sorties de gaz mais ne vise pas à protéger le robinet contre les chutes. En outre, une bouteille ainsi équipée n'est pas destinée à être transportée mais, au contraire, à être positionnée à demeure dans une armoire de distribution de gaz ou mélanges gazeux. De même, son utilisation se fait uniquement en position verticale.In addition, the document US Patent 5,440,477 proposes a gas cylinder equipped with a gas management system formed of a screen electronic box that mounts around the valve block. This management system makes it possible to manage the gas outlets but does not aim at protecting the faucet against falls. In addition, a bottle thus equipped is not intended to be transported but, on the contrary, to be permanently positioned in a cabinet for dispensing gas or gas mixtures. Similarly, its use is only in a vertical position.

Le document EP-A-2339222 enseigne un ensemble de distribution de gaz comprenant une bouteille de gaz comprenant un capotage recouvrant le haut de la bouteille. Le bloc robinet fait saillie hors du capotage. Deux poignées de transport, fixées au capotage, sont agencées latéralement et de part et d'autre du bloc robinet. Un écran digital est porté par la base du capotage.The document EP-A-2339222 teaches a gas distribution assembly comprising a gas cylinder comprising a cowling covering the top of the bottle. The valve block protrudes out of the cowling. Two transport handles, attached to the cowling, are arranged laterally and on either side of the valve block. A digital screen is carried by the base of the cowling.

Au vu de cela, le problème qui se pose est de proposer un ensemble de distribution de gaz permettant de fournir à l'utilisateur non seulement des informations relatives au gaz délivré par la bouteille (type de gaz, pression, autonomie) mais aussi, si désiré, d'autres informations utiles (date, heure, lieu, nom de l'hôpital...), et de les rendre facilement accessible, c'est-à-dire lisibles par l'utilisateur, et donc d'éviter tout ou partie des problèmes susmentionnés. De plus, la bouteille doit pouvoir être transportée facilement d'un endroit à un autre et utilisée aussi bien en positions verticale et horizontale, et que les informations restent visibles et lisibles quelle que soit la position d'utilisation adoptée. Enfin, une protection du bloc robinet de distribution de gaz contre les chocs et les chutes doit également être assurée.In view of this, the problem is to propose a gas distribution assembly to provide the user not only information on the gas delivered by the bottle (type of gas, pressure, autonomy) but also, if desired, other useful information (date, time, place, name of the hospital ...), and to make them easily accessible, ie readable by the user, and thus to avoid any or some of the above problems. In addition, the bottle must be able to be easily transported from one place to another and used both vertically and horizontally, and the information remains visible and legible regardless of the position of use adopted. Finally, protection of the gas distribution valve block against shocks and falls must also be ensured.

L'invention va maintenant être mieux comprise grâce à la description détaillée suivante, faite à titre illustratif mais non limitatif, en référence aux figures annexées parmi lesquelles :

  • la Figure 1 représente un premier mode de réalisation du capotage de protection d'un ensemble bouteille/bloc robinet/capotage selon l'invention, et
  • la Figure 2 représente un second mode de réalisation du capotage de protection d'un ensemble bouteille/bloc robinet/capotage selon l'invention.
The invention will now be better understood thanks to the following detailed description, given by way of illustration but without limitation, with reference to the appended figures among which:
  • the Figure 1 represents a first embodiment of the protective cowling of a cylinder / valve block / cowl assembly according to the invention, and
  • the Figure 2 represents a second embodiment of the protective cowling of a bottle / valve block / cowl assembly according to the invention.

Les Figures représentent deux modes de réalisation d'un capotage de protection 1, couramment appelé « chapeau », agencé autour d'un bloc robinet (non visible), à savoir un robinet avec ou sans détendeur intégré, lui-même fixé sur le col d'une bouteille de gaz 2, de préférence le bloc robinet est de type RDI.The figures represent two embodiments of a protective casing 1, commonly called "cap", arranged around a valve block (not visible), namely a tap with or without built-in regulator, itself attached to the neck of a gas cylinder 2, preferably the valve block is of type RDI.

La fixation autour du bloc de robinet sur le col de la bouteille de gaz 2 se fait par vissage.The fixing around the valve block on the neck of the gas cylinder 2 is done by screwing.

La bouteille de gaz 2 a typiquement un corps cylindrique en acier et une taille entre 10 et 150 cm, et une contenance de 0,5 à 20 litres (en équivalent eau).The gas cylinder 2 typically has a cylindrical steel body and a size between 10 and 150 cm, and a capacity of 0.5 to 20 liters (in water equivalent).

Le capotage de protection 1 permet de protéger le bloc robinet contre les chocs. Pour ce faire, il comprend un corps de capotage formant une coque protectrice autour d'un volume interne dimensionné pour recevoir le bloc robinet.The protective cover 1 protects the valve block against shocks. To do this, it comprises a casing body forming a protective shell around an internal volume sized to receive the valve block.

Comme on le voit sur les Figures, il est surmonté d'une poignée de portage 6 conçue pour être prise en main par un utilisateur. La poignée de portage 6 est formée d'un matériau rigide, tel un polymère ou un métal ou alliage métallique, et est portée par un ou plusieurs montants-supports 5 reliant mécaniquement le corps de capotage à la poignée de portage 6. Elle est préférentiellement agencée horizontalement, c'est-à-dire perpendiculairement ou quasi-perpendiculairement par rapport à l'axe vertical de la bouteille 2 et du capotage 1. La poignée de portage 6 a une forme longiligne, qu'elle soit rectiligne ou incurvée, typiquement une longueur inférieure à 20 cm, typiquement de 6 à 15 cm.As seen in the figures, it is surmounted by a carrying handle 6 designed to be handled by a user. The carrying handle 6 is formed of a rigid material, such as a polymer or a metal or metal alloy, and is carried by one or more support posts 5 mechanically connecting the casing body to the carrying handle 6. It is preferentially arranged horizontally, that is to say perpendicularly or almost perpendicular to the vertical axis of the bottle 2 and the cowling 1. The carrying handle 6 has an elongated shape, whether rectilinear or curved, typically a length less than 20 cm, typically 6 to 15 cm.

Un ou des montants-supports 5 sont fixés à l'une ou aux deux extrémités de la poignée de portage 6 de manière à permettre à un utilisateur de transporter facilement l'ensemble chapeau/robinet/bouteille au moyen de ladite poignée de portage 6.One or more support posts 5 are attached to one or both ends of the carrying handle 6 so as to allow a user to easily transport the hat / tap / bottle assembly by means of said carrying handle 6.

Dans le mode de réalisation de la Figure 2, la poignée 6 est portée par deux montants-supports 5 reliant mécaniquement les deux extrémités de ladite poignée 6 au corps du capotage 1, alors que dans celui de la Figure 1, elle est portée par un seul montant-support 5 reliant mécaniquement une des extrémités de la poignée 6 au corps du capotage 1, l'autre extrémité de la poignée 6 venant se raccorder directement au corps de capotage 1 dont la face avant 11 est conformée pour s'étendre, c'est-à-dire se projeter, vers le haut.In the embodiment of the Figure 2 , the handle 6 is carried by two support posts 5 mechanically connecting the two ends of said handle 6 to the casing body 1, while in that of the Figure 1 it is carried by a single support member 5 mechanically connecting one of the ends of the handle 6 to the casing body 1, the other end of the handle 6 coming directly connected to the casing body 1 whose front face 11 is shaped to extend, that is, to project, upward.

Dans tous les cas, le corps du capotage 1 est typiquement en un matériau de type polymère et/ou métal, préférentiellement en matériau plastique, tel que PVC, PE, PET, PP, PMMA, PU, PA... De même, les montants-supports 5 peuvent être formés d'un matériau plastique, comme le corps du capotage 1, mais aussi en alliage d'aluminium ou tout autre matériau métallique. Ils peuvent être fixés à la poignée 6 par vissage ou soudage, par exemple, ou formés d'une seule pièce.In all cases, the casing body 1 is typically made of a polymer and / or metal type material, preferably made of plastic material, such as PVC, PE, PET, PP, PMMA, PU, PA. support posts 5 may be formed of a plastic material, such as the body of the cowling 1, but also of aluminum alloy or any other metallic material. They can be attached to the handle 6 by screwing or welding, for example, or formed in one piece.

Le capotage de protection 1 présente par ailleurs une ouverture ou logement 4 aménagé au niveau de la partie supérieure 1a, encore appelée partie haute, de la face avant 11 du capotage de protection 1, au sein duquel logement 4 vient se loger un écran 3 d'affichage électronique permettant d'afficher différentes informations utiles à l'utilisateur. La partie inférieure lb, encore appelée partie basse, du capotage 1 est située au niveau de la bouteille 2.The protective casing 1 also has an opening or housing 4 arranged at the upper part 1a, also called the upper part, of the front face 11 of the protective casing 1, in which housing 4 is housed a screen 3 d electronic display for displaying various useful information to the user. The lower part lb, also called the lower part, of the cowling 1 is located at the level of the bottle 2.

L'écran 3 d'affichage électronique est par exemple un écran LCD.The electronic display screen 3 is for example an LCD screen.

Par exemple, l'écran 3 est conçu et apte à afficher une information choisie parmi l'heure, la date, le débit de gaz délivré par le robinet, la pression du gaz dans la bouteille 2, l'autonomie en gaz de la bouteille 2, l'autonomie de la source électrique, la température ambiante, une alarme, le nom de l'établissement de soins ou autre.For example, the screen 3 is designed and able to display information selected from the time, the date, the gas flow delivered by the tap, the gas pressure in the bottle 2, the gas autonomy of the bottle 2, the autonomy of the power source, the ambient temperature, an alarm, the name of the care facility or other.

Afin de pouvoir afficher tout ou partie de ces informations, on prévoit en outre un ou plusieurs capteurs, tel un ou des capteurs de pression, de débit, de position de l'organe de commande (levier ou volant), de présence de l'utilisateur ou autre.In order to be able to display all or part of this information, provision is also made for one or more sensors, such as one or more sensors for pressure, flow, position of the control member (lever or flywheel), presence of the user or other.

Les mesures opérées par ce ou ces capteurs sont traitées par des moyens de traitement d'informations, par exemple un microprocesseur associé à un ou plusieurs algorithmes, puis éventuellement stockées au sein d'une mémoire de stockage d'informations, et enfin transmises, via une connectique adaptée, à l'écran électronique 3 sur lequel elles peuvent être affichées.The measurements performed by this or these sensors are processed by information processing means, for example a microprocessor associated with one or more algorithms, then optionally stored in an information storage memory, and finally transmitted via a suitable connector, the electronic screen 3 on which they can be displayed.

Une source électrique, par exemple une ou plusieurs batteries ou piles électriques, alimente en courant électrique l'écran 3, ainsi que le ou les capteurs, et les moyens de traitement d'informations, en particulier le microprocesseur, et éventuellement la mémoire de stockage d'informations.An electrical source, for example one or more batteries or electric batteries, supplies electrical power to the screen 3, as well as the sensor or sensors, and the information processing means, in particular the microprocessor, and possibly the storage memory. information.

Les moyens de traitement d'informations et la source électrique sont agencés dans un (ou plusieurs) logement interne aménagé dans le capotage 1.The information processing means and the electrical source are arranged in one (or more) internal housing arranged in the cowling 1.

Comme illustré sur les Figures 1 et 2, une surface plane 9 est aménagée au niveau de la face avant 11 de la partie supérieure la du capotage de protection 1, au sein de laquelle surface plane 9 est aménagées le logement 4 recevant l'écran d'affichage électronique 3.As illustrated on Figures 1 and 2 , a flat surface 9 is arranged at the front face 11 of the upper part of the protective cowling 1, within which flat surface 9 is arranged the housing 4 receiving the electronic display screen 3.

Dans le mode de réalisation de la Figure 1, le logement 4 est aménagé dans la partie de face avant 11 conformée pour s'étendre, c'est-à-dire se projeter, vers le haut et faisant office de montant-support pour la poignée de portage 6.In the embodiment of the Figure 1 , the housing 4 is arranged in the front face portion 11 shaped to extend, that is to say, projecting upwardly and acting support post for the carrying handle 6.

De préférence, l'axe BB de l'écran 3 est oblique par rapport à l'axe AA du capotage 1 et de la bouteille 2, c'est-à-dire que lesdits axes AA et BB forment entre eux un angle α inférieur à 70°, de préférence inférieur à 60°, comme schématisé en figure 1.Preferably, the axis BB of the screen 3 is oblique with respect to the axis AA of the cowling 1 and the bottle 2, that is to say that said axes AA and BB form between them a lower angle α at 70 °, preferably less than 60 °, as shown schematically in figure 1 .

Selon le mode de réalisation considéré, l'écran 3 est agencé dans le logement 4 aménagé dans la surface plane 9 de manière à ce que sa vitre supérieure affleure au niveau de ladite surface plane 9, ou soit légèrement en retrait au sein du logement 4 ou, à l'inverse, légèrement en saillie vers l'extérieur par rapport à la surface plane 9.According to the embodiment considered, the screen 3 is arranged in the housing 4 arranged in the flat surface 9 so that its upper window is flush with said flat surface 9, or is slightly set back within the housing 4 or, conversely, slightly protruding outwards with respect to the flat surface 9.

Un tel agencement de l'écran 3 en position haute la et en façade 11 du capotage 1, avec sa vitre de lecture inclinée de manière à former un angle α donné (< 70°) par rapport à l'axe AA du capotage 1 et de la bouteille 2, permet de faciliter considérablement à l'utilisateur la lecture des informations délivrées par l'écran 3 d'affichage électronique et d'éviter des erreurs de lecture.Such an arrangement of the screen 3 in the upper position 1a and the front 11 of the cowling 1, with its reading glass inclined so as to form a given angle α (<70 °) relative to the axis AA of the cowling 1 and of the bottle 2, makes it considerably easier for the user to read the information delivered by the electronic display screen 3 and to avoid reading errors.

Par ailleurs, le capotage de protection 1 comprend un organe de commande du débit de gaz, tel un volant rotatif 7 (Figure 2) ou un curseur mobile (Figure 1), contrôlant le débit du gaz traversant le bloc robinet.Furthermore, the protective casing 1 comprises a gas flow control member, such as a rotary wheel 7 ( Figure 2 ) or a moving cursor ( Figure 1 ), controlling the flow rate of the gas passing through the valve block.

Dans le mode de réalisation de la Figure 2, qui est préféré, le volant rotatif 7 est situé en face avant et est agencé autour d'un raccord de sortie de gaz 8 permettant de soutirer le gaz délivré par le robinet.In the embodiment of the Figure 2 , which is preferred, the rotary wheel 7 is located on the front face and is arranged around a gas outlet connection 8 for withdrawing the gas delivered by the tap.

Afin de permettre l'accroche ou l'arrimage de l'ensemble bouteille/bloc robinet/capotage à un support, tel un barreau de lit d'hôpital ou de brancard, le capotage de protection 1 peut comprendre, du côté de sa face arrière, un dispositif d'accrochage 10 pivotant, entre une position totalement repliée, dite « de repos », c'est-à-dire la position adoptée par le dispositif d'accrochage 10 lorsqu'il est rangé et en contact ou quasi-contact du corps du capotage 1 (comme illustré en Fig. 2), et une position totalement dépliée dite « d'accrochage », c'est-à-dire la position adoptée par le dispositif d'accrochage 10 lorsqu'il est complètement sorti et peut être accroché à un support, tel un barreau de lit ou analogue.In order to allow the hooking or securing of the bottle / valve block / cowling assembly to a support, such as a hospital bed or stretcher bar, the protective casing 1 may comprise, on the side of its rear face , a pivoting attachment device 10 between a fully folded position, called "rest", that is to say the position adopted by the attachment device 10 when stored and in contact or near-contact the body of the cowling 1 (as shown in Fig. 2 ), and a completely unfolded position called "hooking", that is to say the position adopted by the fastening device 10 when it is completely out and can be hooked to a support, such as a bed rail or the like.

Le dispositif d'accrochage 10 comprend deux bras parallèles pivotant par rapport au corps du capotage, lesquels bras forment des crochets d'arrimage. De préférence, les deux bras pivotants sont reliés l'un à l'autre, par exemple via un élément de liaison, de manière à pivoter simultanément l'un avec l'autre.The attachment device 10 comprises two parallel arms pivoting relative to the casing body, which arms form lashing hooks. Preferably, the two pivoting arms are connected to each other, for example via a connecting element, so as to pivot simultaneously with each other.

Le dispositif d'accrochage 10 est donc conformé et dimensionné, en particulier les deux bras, pour permettre son arrimage ou accrochage à un barreau de lit d'hôpital ou de brancard, c'est-à-dire à un support de forme généralement tubulaire.The attachment device 10 is therefore shaped and dimensioned, in particular the two arms, to allow it to be secured or hooked to a hospital bed or stretcher bar, that is to say to a support of generally tubular shape. .

Une bouteille de gaz 2 équipée d'un capotage 1 selon l'invention est particulièrement adaptée pour un usage en milieu médical, en particulier elle convient au stockage de tout gaz ou mélange gazeux médical, en particulier de type oxygène, air, N2O/O2, He/O2, NO/azote ou autre.A gas cylinder 2 equipped with a cowling 1 according to the invention is particularly suitable for use in a medical environment, in particular it is suitable for the storage of any gas or medical gas mixture, in particular of oxygen, air, N 2 O type. / O 2 , He / O 2 , NO / nitrogen or other.
